scikit-build is a Python build system for CPython C/C++/Fortran/Cython extensions using CMake.
The scikit-build package is fundamentally just glue between the setuptools
Python module and CMake_.
The next generation of scikit-build, scikit-build-core_, is currently under development.
This provides a simple, reliable build backend for CMake that does not use
setuptools and provides a lot of new features. Scikit-build-core can also power
a setuptools-based extension system, which will eventually become the backend
for scikit-build (classic). If you do not require extensive customization of
the build process, you should consider trying scikit-build-core instead of
scikit-build.
To get started, see this example <https://scikit-build.readthedocs.io/en/latest/usage.html#example-of-setup-py-cmakelists-txt-and-pyproject-toml>. For more examples, see scikit-build-sample-projects <https://github.com/scikit-build/scikit-build-sample-projects>.
This release fixes issues with setuptools 74, and avoids a warning from recent versions of wheel. Android and iOS are now included in known platforms.

scikit-build 0.17.3 returns an empty string from get_python_library if no
Python library is present (like on manylinux), where 0.17.2 returned None, and
previous versions returned a non-existent path. Note that adding REQUIRED
to find_package(PythonLibs will fail, but it is incorrect (you must not
link to libPython.so) and was really just injecting a non-existent path
before.

PyCMake was created at SciPy 2014 in response to general difficulties building C++ and Fortran based Python extensions across platforms. It was renamed to "scikit-build" in 2016. Scikit-build-core was started in 2022.
These issues are likely to be addressed in upcoming releases, and are
already addressed in scikit-build-core_.

some cases (like rebuilding with a different Python interpreter).We are also working on improving scikit-build, so there are some upcoming changes and deprecations:
